REGISTER FOR PUIYIISL To all whom it may concern.' l

Be it known that I, LOUIS RANDOLPH Conn, a citizen of the'United States, residing in the borough of Brooklyn of the city of New York, in the State of New York, have invented certain new and useful Improvements in Registers for Pumps, of

which the following isa specification, reference being had to the accompanying drawings. forming a part hereof.

The invention relates to means for registering the operation of a moving part or mechanism such as the rod or plunger of a pump, andone of the objects of the invention is to provide means whereby both theV moving part and the registering mechanism may be held against operation except under predetermined conditions.

A further object of theinvention is to provide means whereby the locking and registering mechanism may be released by a plurality of independent locks.

Another object of the invention is to pro-v vide means whereby the registering mechanism shall be operated at every movementor stroke of the moving part or shall be operated only at each alternate movement' or stroke as desired.

The various other objects of the invention will be more fully set forth in the following descriptions of one form of mechanism and certain illustrative modifications thereof, embodying my invention, which consists in the new and novel features of construction and combinations ot' parts hereinafter vsetforth.

In the accompanying drawings-Figure l is a front elevation of my improved mechanism as applied to and operated by the rod or plunger of a pump (not shown).

mechanisms between the driving .shaft and one of the registering devices. Fig. 11 represents an end View of the barrel of the lock. Fig. 12 represents a modified construction adapted to register only movement in o-ne direction of the actuating rack. Fig. 13 is a detail view of the clutchmechanism shown in Fig. 12. Fig. 14 yrepresents a side elevation of a modified form of locking bar. Fig. 15 is a diagrammatic view showing actuating rack integral with the pump plunger or other moving part.

Referring to the particular device eml'bodying my invention shown in thel a'ccompanying drawings, the registering mechanism is operated by and registers the extent of movement of any moving part as the rod or plunger 1 of a pump (not shown) which performs a definite amount of work, such as supplying a certain quantity of liquid by a predetermined movementor stroke. The rod or plunger may be securely connected by "any suitable meansas a stud 2 to the movable Imember 3 having a rack 4 secured thereto or formed integral therewith. The rack is movable in and guided by a hollow standard 5 which may be secured to any suitable support as the flvoornor table 6 by a base plate The registering and locking mechanism is contained in a casing 8 secured to the standard by any suitable means as the screw or bolt 9. The casing is preferably made in two parts 10 and 10a whichmay be secured together by a lug 11 formed integral with one partand passing through an eye 1la provided in the other part and engaged by a bar 12 which may be locked against'removal in any well known manner. Within the casing a pinion 14 keyed to a transverse shaft 15 is constantly in mesh with the rack, and preferably a. bevel gear 16 is secured to said shaft which is constantly in mesh with gear wheels 17 and 17a loosely mounted upon the driving shaft 18 of the registering devices. A ratchet disk 19 is keyed to the shaft 18 between the gears which are adapted to engage with said disk when rotated in opposite directions by means of pawls 20 which are normally held in engagement with the teeth on the disk by means of springs 21, so that the pawl 0i one gear will ride idly when the pawl on the other gear is in operative engagement with the disk. A slot 22 is provided in one of the gears that access may be had' to one of the ed from the disk *if desired. Suitgble sight openings 24 are provided in the casing to permit inspection of the dials of the registering devices.

A plurality of registering devices 25, which may be of lany preferred or well known construction, are mounted in the casing 8. Said devices are driven from the shaft 18 through ya corresponding number of clutch mechanisms 26, each of which com rises a clutch member 27 keyed to the shafli and a female member 28 loosely mounted on the Shaft and operatively engaged with the driving gear 29 of the corresponding registering device by suitable means as a pin 30 in the one part which seats in a socket 31 in the other part and thus permits movement of the female clutch member with relation both to the male member of the clutch and to the gear. A spring 32 normally holds the clutch members in engagement. Y

A plurality of locks 34 corresponding in number and position with the registering devices are. mounted iny the casing and are arranged in a row parallel with the registering devices and a suitable distance therefrom. Each lock is operated by'a key in' the usual manner and preferably the locks are of a type requiring individual keys so that it will be impossible to operate any lock except with the particular key fitted thereto. The locks comprise a barrel` tumblers, pin 35 and guard 36 which may be of any well known construction. If desired a letter 37 or other indicia may be placed on the casing contiguous to each lock so that the same may be designated.

A locking bar 38 is arranged between the locks and the registering devices and is guidedvin any suitable manner as by an integral flange 39 sliding on the casing and held against lateral displacement by guide 40. At its forward end the bar is provided with teeth 41 adapted to engage the rack or with a jaw 42 (Figs. 12 and 14) adapted to engage the pinion 14. A. spring 44 engages with the bar and normally holds the same in its locking position. An irregular shaped opening or slot 45 is provided in the bar opposite each lock and the pin 35 projects therethrough. Each slot comprises a longitudinal portion 45a and a vertical or inclined portion 45h, one side of which, as 46, is adapted to eng-age with the pin 35. The guard 36 preferably engages with the guidingY flange 39 when t-he locking bar has reached its retracted position and prevents further rotation of the lock barrel and also assists the pin 35 in holding the bar in'its retracted position.

An auxiliary bearing shaft 47 is secured in the casing parallel to the shaft 18 and has a. plurality of sleeves 48 movably mounted thereon between the registering devices and the locks and corresponding in number and position therewith. Oppositely projecting arms are formed integral with each sleeve, one of said arms as 49 loosely contacting with the movable clutch member of one of the registering devices and the other arm as 50 being secured to the pin of the corresponding locking device. Consequently the movable clutch `member will be disengaged positively when the locking bar .is thrown into -its forward or locking position by the rotation of the pin and will be released when the locking bar is retracted by the pin, thus permitting the spring 32 to bring the clutch members into engagement.

As shown in Fig. 12 of the drawings the registeringL devices may 'be operated from the pinion 14 through a gear 51 operatively connected with the shaft 18 by pawl and ratchet 52 so that the registering device will be actuated only upon alternate strokes of the operating handle. In this construction the rack does not engage directly with the pinion 14 but engages intermediately with the inion 54 mounted vupon a shaft 55 paralle to the shaft 18 and having suitable bearings in the casing 8. As indicated in Fig. 15, the connection can be made between the rack and gear 54 through the train of gears 56, 57 and 58. In this case the rack may be formed upon and integral with the moving part such as the pump plunger 1.

lVhen the lock is closed or in its locked position, not only is the actuating or moving member such as the pump plunger held against movement but the registering devices also are disconnected from their driving shaft. When any one of the plurality of locks is opened, however, the pin 35 acting against the side 46 of the adjacent slot 45 in the locking bar retracts said bar against the tension of the spring 44 and simultaneously releases the clutch member of the corresponding registering device, thus permitting the spring 32 to bring the clutch members into engagement. The construction of the slots is such that the bar will be retracted by rotation of the pin 35 secured to any one of the lockssince the horizontal slot member permits independent movement of the locking bar with relation to the remainder of the pins. Any movement of the moving part such as the pump plunger after the locking bar has been retracted will be indicated and recorded upon the registering device. In'the construction shown in Figs. 12 and 15 only the alternate strokes or movements of the moving member will be recorded, but in the construction shown in Fig. 3 each movement of the moving member will be recorded on the registering device unless one of t-he awls 2O is disconnected by a suitable instrumentv inserted through the slot 22 whereupon thesaid` con'- struction likewise will record only the alternate movements of the moving part. When the lock key is again turned to its starting position, the clutch member 28 is positively disengaged and the locking bar is released by the pin 35, thus permitting the spring 44 to force the .locking bar into engagement with the moving part and hold the same against further movement.

By means of this construction an accurate record may be kept of the work as determined by the number of movements of the moving part which is performed by each salesman or foreman intrusted with a key to one of the locks. In case the keys are given to the managers and foremen of different departments of the samefactory or establishment where this apparatus may be used, a record willV be kept of the article dispensed or controlled by the moving part used by each particular department.

Although the apparatus has been show and described asbeing attached lto the rod or plunger of a pump it is'evident that the apparatus may be used for a great number and variety of purposes and for recording the operation of almost any machine or device whatsoever which embodies a moving part regardless of the purposewfor which such machine or device is used. i

It is obvious that various changes in details of construction and arrangement. may be made to suit different conditions of use, and the invention, therefore, is not restricted to the precise details of construction and arrangement shown and described and that all such changes are within the scope of the. invention provided the means set forth in the following claims be employed.
